How to choose a good battery charger

In order to choose the best charger for a car battery, you first need to decide on its type, for which batteries it is suitable, and also determine for yourself the technical parameters and the functionality you need.

Current and voltage

The first important parameter is the battery charge current. Its value is chosen in accordance with the capacity of a particular battery. namely, the maximum charge current is 10% of the capacitance value. For example, to charge a battery with a capacity of 60 Ah, the maximum allowable current should not exceed 6 Amperes. However, in practice it is better to use a current in the range of 5 ... 10% of the capacitance value.

By increasing the charge current, you can charge the battery faster, but this can lead to sulfation of the plates and a quick failure of the battery. Conversely, the use of lower currents contributes to the extension of its service life. True, when charging with low currents, the charging time will increase.

Online calculation of battery charging time. Calculator for calculating how much you need to charge a car battery with a charger

You can charge a car battery to 8V for 12-12,5 hours in two ways: direct current and voltage. The estimated full charge time is calculated on a calculator using the formula I=Q*k Read more

Be sure to take into account the voltage of the charger. It must match the battery voltage. There are chargers for 6 volts, 12 volts, 24 volts. Most batteries used in passenger cars are 12 volts. Chargers that allow you to set the voltage when there is a need to charge batteries of different voltages.

When choosing a starting and starting-charging device, you also need to take into account the minimum starting current. To determine the minimum allowable value of the starting current, you need to multiply the battery capacity by three. For example, if the battery capacity is 60 Ah, then the minimum allowed starting current should be 180 Amps. That is, the device must produce from 180 amperes or more.

Transformer and pulse chargers

The next important parameter is the type of charger. There are two basic classes - transformer and pulse charging. Transformer, respectively, operate on the basis of a built-in transformer and have manual settings. note that transformer chargers are not suitable for batteries made using GEL and AGM technology. Conversely, it is a good option to work with the classic lead-acid batteries that are most common among car enthusiasts.

Transformer chargers are quite simple, and their price is much lower than that of electronic (pulse, "smart") chargers. They have a large mass and dimensions. Typically, transformers are installed on start-up chargers, which initially give a large current to "warm up" the battery. also one advantage of transformer charging - high reliability, including during jumps in the voltage value in the electrical network.

As for pulse chargers, they work on the basis of electronics. Accordingly, they can be used to charge batteries of any type. In fairness, it should be noted that at present, in most cases, it is precisely pulse charging.

Automatic, programmable and manual charging

Manual chargers are simpler and cheaper devices. Depending on the model, they can adjust the voltage and charge current. In most cases, the adjustment is based on the current, which must be manually reduced as the voltage in the battery being charged increases. Often these are ordinary transformer chargers designed to charge lead-acid batteries.

As for the automatic ones, in the simplest case, the device maintains a constant voltage when charging (about 14,5 volts) and, as it charges, gradually reduces the current in automatic mode. Another option for an automatic charger is DC charging. There is no voltage regulation. Often, such chargers have additional functions, for example, auto-off. That is, when the maximum allowable voltage is reached, the device simply turns off.

Another option for automatic chargers is with no flexible settings. Usually they are chargers that are connected to the battery and to the outlet. further, "smart" electronics independently selects charging modes in accordance with the type of battery, its capacity, condition and other characteristics. Please note that such automatic charging without the possibility of flexible settings will be the most optimal for novice motorists, or drivers who do not want to “bother” with battery charging modes. This is very convenient, but such charges are not suitable for calcium batteries.

The next type of device is the so-called intelligent. They also belong to the impulse class, but at the same time they also have a more advanced control system. Their work is based on the use of electronics (microprocessor devices).

Intelligent chargers allow the user to select the functions and parameters for charging certain batteries. namely, their type (gel, acid, AGM and others), power, charging speed, switching on the desulfation mode, and so on. However, smart chargers have current limits. Therefore, in addition to the price, this parameter must also be taken into account. Usually, the charging case (or instructions) directly indicates what types of batteries they can work with.

The most "advanced" option is programmable chargers. They allow you to set the charging mode. For example, a few minutes with one tension, a few with another, then a break, and so on. However, such devices are suitable only for those motorists who are well versed in this. The natural disadvantage of such models is their high price.

Other charger classifications

Chargers are also divided according to the type of battery start. There are pre-launch, launch-charging and launchers.

To the distinctive features prelaunch This applies to the fact that they can briefly deliver a charge current much higher, 10% of the battery capacity. This is done in order to “cheer up” the battery before starting. This is necessary, for example, if the battery is significantly discharged and/or if the battery has been idle for a long time. Alternatively, use the battery in extremely low temperatures.

The next type according to the specified classification is starting-charging. Such chargers are connected to batteries that are installed and connected to the vehicle's electrical system. This is done in the case when the battery is significantly discharged and it is difficult for it to start the internal combustion engine on its own. In start mode, these devices provide a significant current for several seconds (for example, 80 ... 100 Amperes for 5 seconds). It depends on the specific charger model. The use of a starting charger is strictly regulated by the operating instructions, since its operation is associated with overheating of the transformer, wires, and load on the battery.

Starter-charging devices are a universal solution for an ordinary car enthusiast, since they allow you to simply charge the battery and start the internal combustion engine when it is significantly discharged. On some chargers, you can find the definition of "diagnostic". Behind this word is usually the ability of the unit to monitor the voltage on the battery and / or the voltage supplied from the generator. In most cases, this is, in fact, only a built-in voltmeter. A starter charger is the best option for using it in a garage..

The next type is launchers (another name is “boosters”). They are high capacity batteries that need to be charged beforehand. It is compact enough to be carried from the garage or home to the parking lot. The unit is capable of delivering a very large current, and is able to start the car's internal combustion engine even with a "dead" battery. This is especially true during the onset of cold weather. The price of such devices is quite high, from 9000 to 15000, so you need to make a choice of a machine booster personally for your car.

Many chargers have two charging modes - standard and accelerated. The fast mode is worth using when you need to go urgently, and there is no time for a long load. In addition, the "stress" mode sometimes allows you to "revive" the battery after a deep discharge. Please note that it is harmful to use the boost mode (English name - Boost) frequently, as this can shorten the battery life. But it is still useful if the charger has the ability to work in accelerated mode. It can be used, for example, in the case when in the morning in winter you need to quickly charge a battery discharged overnight, or even similar in the field after a long stay, provided that it is in the trunk of a car.

Choosing a charger by battery type

With conventional acid batteries, any charger or start-charger can work. Therefore, to work with it, you can purchase an inexpensive charger with suitable technical characteristics.

To charge other batteries, you need to use only impulse chargers. note that To charge calcium batteries, a voltage of about 16,5 volts is needed. (may differ for different models). Therefore, programmable chargers are best suited for them. They usually have built-in programs for charging calcium, GEL, AGM and other batteries. In addition, for programmable chargers, a car enthusiast can come up with a charging algorithm on their own.

Price and build quality

When choosing a good charger for a car battery, you need to consider their price and workmanship. The cheapest will be transformer chargers. However, they can only be used to work with acid batteries. Average in price are automatic chargers. They are, in fact, universal, and with their help you can work with batteries of any type. The price is higher than that of transformers. The most expensive, but also the most convenient to use, are intelligent or programmable. Depending on the maximum current strength and the availability of additional functions, the cost will differ.

Regardless of the power and type of a particular charger, you should always pay attention to the quality of the product. namely, the correctness of writing the technical parameters on the body, the quality of the seams on the body. If there are errors, most likely the chargers are made in China, which may indicate a low quality product. Be sure to pay attention to the wires - their cross-sectional area (thickness) and the quality of the insulation. Be sure to pay attention to the clips ("crocodiles"). For many domestic chargers, they break or disintegrate even after a short period of operation.

Additional functions

When choosing a charger, you should also pay attention to the presence of additional functions. First - desulfation mode. Relevant for the use of classic lead-acid batteries. This function makes it possible to partially restore the capacity of a battery that has been subjected to frequent full discharges.

The following function is battery health check mode. This is true for maintenance-free batteries, when the car owner does not have the opportunity to check which of the cans is out of order, and in general how suitable the battery is for further operation. it is also desirable for the charger to be able to check the actual capacity of the battery.

A useful function of any charger is to turn off the unit if it is incorrectly connected to the battery (the so-called "fool protection"). also one useful protection is against short circuit.

Hack and predictor Aviator

To work with an acid battery, almost any charge will do. For a calcium battery, it is better to buy a programmable charger (but not an intelligent one). For GEL and AGM batteries, it is better to use programmable or intelligent chargers with a choice of battery type.

It is not recommended to buy automatic chargers of a universal type without the ability to select the type of battery, current and other characteristics. In extreme cases, you can use such charging from well-known manufacturers, such as Bosch, Hyundai. They have similar settings. Cheap Chinese analogues do not have them.
